I've done quite a bit of searching but cannot seem to find the answer to my question. The early 350z's have a narrowband sensor whereas the later models sport wideband sensors.

I am looking to replace the stock narrowband sensors with the stock wideband sensors. I have read this is not possible on a stock ECU but I have installed a Haltech Platinum Pro PNP Standalone ECU that has compatibility for both the normal and Rev up VQ35DE engines. So I think it is possible that it may work.

Has anyone else done this and can shed some light on this?

Thank you in advance.

 

The connectors for a wideband and narrow band are different. You would have run harness from the wide band to the main harness.
